According to a Tweet by John Carmack himself, the source code of Doom 3 will be released into the wild very soon, just as promised at Quakecon 2011:
It's great that id Software is so open-minded about their games and intellectual property. I can't wait to see what the community will come up with once they get their hands on this. I foresee a remake of the original Doom based on the engine of Doom 3.
Aw man...now I need a change of pants.
